In the game PoP: SoT, in-game water effects cause the following glitches: the
screen turns to black intermittently, as you rotate the camera with the mouse.

How to reproduce the issue in the demo:
1. Start the demo, create a new profile. If you suffer from the 'fog effect'
bug, go to options and turn off 'Fog effect', but make sure 'Water effects' are
enabled.
2. Start a new game, move your character into the light (skip the video), when
your character re-appears switch to first-person view (by pressing 'F') and
turn the camera with the mouse >> see the intermittent black-outs.

During gameplay the console is flooded with the following two lines of
messages:

err:d3d_shader:shader_glsl_select >>>>>>>>>>>>>>>>> GL_INVALID_OPERATION
(0x502) from glUseProgramObjectARB @ glsl_shader.c / 4718
err:d3d_shader:shader_glsl_load_constants >>>>>>>>>>>>>>>>>
GL_INVALID_OPERATION (0x502) from glUniform4fvARB @ glsl_shader.c / 757

Workaround: disable in-game water effects or disable pixel shader support in
winecfg's Graphics tab.
